﻿The forced position communication object can be initialised after bus voltage return. The brightness status of the dimming output can be influenced when the forced position function is activated.

*No forced position*: No forced position is activated after bus voltage return. Reaction of the dimming output according to the parameter "Behaviour after bus voltage return".

*Forced position active, switch on*: The forced position is activated. The dimming output is switched on to the brightness value predefined by the parameter "Brightness for forced position 'active, switch on'".

*Forced position active, switch off*: The forced position is activated. The dimming output is switched off under forced control.

*State before bus voltage failure*: The forced position state last selected and internally stored before bus voltage failure will be tracked after bus voltage return. An ETS programming operation deletes the stored state (reaction in that case same as with "no forced position active"). If the tracked state corresponds to "No forced position", the force-independent parameter "After bus voltage return" (parameter page "Dimming output... -> DO... - General") will be executed on return of bus voltage.
